Infrared Thermography of Divertor ELM Heat Loads on TCV

Edge Localised Mode (ELM)-induced heat loads, in particular divertor heat loads present one of the main challenges in adopting nuclear fusion as an industrial-scale energy source. At present, the type-I ELMy plasma regime is chosen as the most suitable ope ...

"Snowflake" H Mode in a Tokamak Plasma

Basil Duval, Jean-Marc Moret, Olivier Sauter, Stefano Coda, Benoît Labit, János Márki, Andreas Pitzschke, Francesco Piras

An edge-localized mode (ELM) H-mode regime, supported by electron cyclotron heating, has been successfully established in a snowflake (second-order null) divertor configuration for the first time in the TCV tokamak. This regime exhibits 2 to 3 times lowe ...

Snowflake divertor experiments on TCV

Basil Duval, Jean-Marc Moret, Olivier Sauter, Stefano Coda, Benoît Labit, János Márki, Andreas Pitzschke, Francesco Piras

An ELMy H-mode 'snowflake' (SF) divertor is established and studied for the first time in the TCV tokamak. The H-mode access and the edge localized mode (ELM) dynamics are compared with a conventional single-null diverted configuration. The SF configuratio ...

ELM induced divertor heat loads on TCV

Richard Pitts, Jan Horacek, János Márki

Results are presented for heat loads at the TCV outer divertor target during ELMing H-mode using a fast IR camera. Benefitting from a recent surface cleaning of the entire first wall graphite armour, a comparison of the transient thermal response of freshl ...

Sheath heat transmission factors on TCV

Richard Pitts, Jan Horacek, Francisco Sanchez, János Márki

Despite its importance in determining the calculated surface power flux predicted, for example, by scrape-off layer simulation codes, the sheath heat transmission factor, gamma remains a quantity whose theoretically predicted value has rarely been tested e ...

SOLPS5 modelling of the type III ELMing H-mode on TCV

Roland Behn, Richard Pitts, Marco Wischmeier, Jan Horacek, János Márki, Barbora Bruant Gulejová

Although ohmic H-modes have long been produced on TCV and the effects of ELMs at the divertor target studied in some detail, no attempt has yet been made to model the scrape-off layer (SOL) in these plasmas. This paper describes details of the first such e ...
